If you're looking for a non web QR generator with lots of options try Zint. https://www.zint.org.uk/ It's the only option I have found that doesn't seem to lock out any features. You want to control the error correction? Got it. Render in color? No problem. Batch convert 1000 lines of text into 1000 individual images. It took less than a second. It even does Datamatrix and other non QR encodings.
